OIL BURNER.

Application filed December 12, 19231. Serial No. 680,202.v

To all' vwhom z'zf may concern.'

Be it known that I, VILLIAM H. MCCARRY, a citizen of the United States, residing at Pittsfield, in the Vcounty of Berkshire and State of Massachusetts, have invented ,cer-

i tain new and useful Improvements in Gil Burners, of whichlthe following is a specification, reference being had therein to the accompanying drawings. l f

This invention relates to an oil burner, and the ,object of theinvention is the production of a simple andV efficient oil burning device which comprises a minimum number of parts and which is practical in operation.

/Vith this and other objects in View, my invention Ycomprises certain ynovel combinations, constructions and arrangements 'of parts as` will be hereinafter described, illustrated in the accompanying drawings, and more particularly 'pointed out in thevappended claim. l

' In the drawings:

Figure 1 is a vertical, longitudinahsectional View of a device constructed in accordance with the present invention, while Figure 2 is atop Vplan view of the same,

showing the crown plate removed.

Figure 3 is a view, in side elevation, while,

Figure 4 is an end view, in elevation, of the device.

Figure 5 is a fragmentary, sectional view of a modified form of the burner, showing particularly the pipe that acts as a vaporizer.

Figure 6 is a view, in side elevation, of one of the sections of a stand or base, sho-wing an oil burner in position thereon.

Figure 7 is a top plan View of a sectional stand.

Figure 8 is a sectional view, taken on line 8 8, Fig. 7, and looking in the direction of the arrows.

Figure 9 is a fragmentary plan view of the crown plate. that fits into the bottoni of the device.

Referring to the drawings'by numerals, 1 designates the body of the device, which is provided around its sides with preferably four outwardly-extending bosses 2, and eX- tending through each boss is a vertical feed or supply pipe 3; each supply pipe 3 has its ends extending below the bottom of the boss in which it is positioned, as shown in Figs. 3 and 1, so that the pipe may be suitably connected to a source of supply. The upper ends e of the supply pipes 3 are bent downwardly inI theform` of a goose neck so 'that :the supply vof oil is discharged downwardly into:- the `uppermost groove 5 of the bodyvl, thebodyl being provideduwitha Vplurality o\f `f4stepip\ed ."k or f tieredgrooves 5 for receiving theoil as it Hows from the upper groove to the next groove. jy y Y l. v,

n Formed lupon thetop edge Vof the body 1, above-.the bosses 2, are upstanding curved flanges 6 which act-as 'shields around the goose neck ends at of the supply pipes. Y

Resting upon the top of the body is a l suitable cover 7 4which has legs 8 (dotted lines) so that the cover 7 will not t tight y upon the top ofthe body, whereby vapors or flames can pass from-under the cover7.

An' integralvba-se flange 9 is formed upon the body and this base flange is provided with a plurality ofhorizontal apertures 10that allow lair to enter the burner. vAn l upstanding flange .11` is `formed upon, the bottom of the body 1 about thelarge 'air inlet opening 15 and pinrstruds 12 are placed upon the bottom of the body (Fig. 1) for receiving the bifurcatedmends 13 (Figs. 1 5,.;

and 9) of the crown'plate 14.

In Fig. 5 there has been sho-wn a modified construction. In this form of burner the bosses 2 are omitted and the bottom of the burner-is provided with a-boss 16 having an opening formed therethrough to receive a distributing pipe 17 and supp-ly pipe 18. rlhis plipe 17 takes lthe place of the pipe 3 and is extended upwardly and provided with a curved upper end portion terminating abo-ve the upper groove 5 inA the walls of the body. The oil will therefore be heated when passing through the pipe 17Vand will be quickly vaporized in the grooves 5. n

The sectional base Aor stand shown in Figs. 6 to 8 comprises sections 19 and 20; section 19 being provided with a plurality of apertures 21 into which lugs` 22 of section 2O extend to lock the sections together, as shown in Figs. 7 and 8. The sections 19 and 20 are provided with depending flanges 23, which iianges act as legs. standing flanges 24 are formed upon sections 19 and 2O to prevent displacement of an oil burner 25, after it is seated within the flanges, on the sectional stand, as shown I in Fig. 6. This sectional structure of. a stand permits ready insertion of the same in a furnace or stove, as one section at a time can be placed through the door, and then after insertion the parts can be quickly assembled.

It is to .be understood that I can make the body Of my burner square, rectangular or in any preferred shape.

Where the base supporting flange 9 is not sufficient, then I can use my sectional stand as shown in Fig. 6.

The operation of the device will result in a saving or" fuel (oil) because of the complete combustion and the `construction is comparatively simple.

It is to be understood that the flanges or shields 6 prevent oil running onto the outside of the body.

Further, the top or cover 7 will assist in mixing air with the vapors and results in the fiames being forced out over the sides of the body into the fire-boxr of the stove or furnace. -in which the burner is operated.

There is an advantage in forming the enlarged portion or boss 15 (Fig. 5) on the bottom, 'tor the bottom can be made of comparatively thin material, whereas a thicker portion is needed for receiving the abutting ends of pipes 17 and 18.

It is also to be understood that by reason i of the feed or supply pipes 3 passing through the bosses 2, the oil is greatly vaporized Since when the burner is operated these bosses will be greatly heated, resulting in the oil passing through pipes that act as vaporizers, on the same principle as pipes 17 consequently, the oil, when the burner is operating, will be discharged into the body in practically a vaporized condition, ready for burning without any loss of fuel.

`While l have described the preferred em bodiment of my invention, and have illustrated the same in the accompanying drawings, certain minor changes or alterations may appear to one skilled in the art to which this invention relates, during the extensive manufacture of the same and l, therefore, reserve the right to make such alterations or changes as shall Ifairly fall within the scope of the appended claim.

What I claim is:

In a device of the class described, the combination of a body provided with a bottom and upstanding walls, one of the walls having its inner surface provided with horizontally extending grooves positioned one above another, said bottom provided with a guarded air inlet opening and between the opening and grooved wall provided with a thickened boss having an open ing therein, a distributor'pipe in said body and having its lower end extending into the opening in said boss and lits upper end portion curved and terminating above the upper groove 'fordepositing oil'tlierein, and a supply pipe having its inner end'extending into said boss for supplying oil lto said distributor pipe. f

in testimony whereof l hereunto a'HiX `iny signature.
